corms INSTRUMENT;

SPECIFICATION forming part of Letters Patent No. 683,809, dated October 1, 1901. Application filed May 3, 1900. Serial No. 15,428. on model.)

To a whont it may concern:

Be it known that I, FERDINAND W. STARR, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Cutting Instruments, of which the following is a specification.

My invention relates to improvements in instruments especially designed for producing a variety of different forms, especially regularly-curved formssuch as circles, e1- lipses,&c.which may be produced by mathematical precision, although the instrument is adapted to produce various other figures or shapes.

The object of the invention is to produce an instrument which shall not only draw or outline the particular form or figure to be produced, but will cut the same in the material upon which the instrument is worked, it being especially adapted for cutting mats for pictures and similar outline-work.

A further object is to improve upon the construction set forth in my prior patent, No. 533,095.

In the accompanying drawings, Figure 1 is a plan view showing the features embodying my invention. Fig. 2 is a side elevation, partly in section, of the same. Fig. 3 is a longitudinal sectional View taken through the operating parts. Figs. 4, 5, 6, and 7 are details of some of the tool holding and adjusting devices.

Like parts are represented by similar letters of reference in the several views.

In its main features the operating parts of this instrument are similar to those shown in the prior patent. A main frame a is supported at the front on legs a. and at the back by a yoke a This frame has a curved groove or slotted opening 01. the curvature of this groove or slot at being the same as set forth A projecting pin 12 on the vibrating lever b engaging in said slot ted opening a causes the head (1 to travel in a straight line at right angles to the longitudinal axis of the machine. A slot b is provided in the vibrating lever b at its point of I- engagement with the pivotal pin b" to permit the longitudinal movement of the vibrating lever 11 The main longitudinal body portion of the frame ais adapted to receive a sliding bar 0, which is provided with suitable guides or hearing portions a, which fit into the grooves of the frame. This sliding bar has a vertical bearing or sleeve 0, from which there is preferably extended a handle 0 In the sleeve or bearing 0 is journaled a rotating head which consists, essentially, of the bar d, extending in opposite directions from a shaft or trunnion (Z and a bar (Z extending in one direction from the shaft or trunnion d and parallel with the bar (1, the said shaft or trunnion (1 being journaled in the sleeve or bearing 0' of the sliding bar 0. The bars (1' and d each have sliding heads at and d fitted thereto and adapted to slide to different positions thereon, so as to be moved to or from the center of the shaft or trunnion, and thus vary the form of the figure to be drawn. These heads are made to fit frictionally in their seats, so that they will remain at the point of adjustment to which they are moved.

I have found in practice that in order to produce perfect results in outlining figures of elliptical or other curved forms it is desirable that the tool which marks the outline should be pivoted or swiveled, so as to readily follow the path whether short or long curves, particularly where the machine is used not only to mark the figure, but also to cut out the material with beveled edges. that it is essential that means he provided for adjusting the tool to the proper position in startingin order that the figure to be produced may be produced within the proper lines. To this end I have constructed the head d" with an auxiliary seat for the reception of a carrier (1 so that the latter may be adjusted laterally across the bar d, as well as longitudinally on the bar. The tool-carrier d" is made in the form of a socket and may have a series of sockets, and the tool-holder is formed with a round shank to fit said socket and a rearwardly-projecting arm (P, which carries the tool proper. The tools may be of any desired construction or kind and the shank d and arm 61 may be formed integral or maybe made separate, as shown in Figs. 5 and 6. Fig. 6 shows a tool in which the cutting-blade is adjustable, the arm d being formed separate from but pivotally connected to the shank d, the cutting-blade being secured in a slot in the arm (Z and held at any desired I have found also angle with the shank (1" by an adjusting-nut on said arm (P. Fig. 7 shows a tool in which the shank and arm are formed integral and a hardened-steel wheel inserted in the latter, for which, if desired, a diamond may be substituted for glass-cutting. The tool is preferably held in position in the socket (Z by means of asmall spring d secured to the side of the socket and bent at its lowerend at right angles, so as to impinge against the tool-shank d, and by the friction thus secured to hold the tool in place, at the same time permitting it to rotate in the socket to produce the necessary swiveled draw-cut-action movement of the tool in the operation of the machine. I have also found it desirable to furnish means for holding the material to be operated upon. To this end I have constructed the lower ends of the legs a with slotted openings through which is slidingly passed a U-shaped frame e to form an adjustable gage. This frame is also preferably provided with a cross-bar e, the ends of which are extended rearwardly to form projections e by means of which the bar may be clamped in different positions to the side of the U-shaped bar e by adjustable clamps e The rear or yoke portion a? of the frame a is also preferably connected yieldingly to the base on which the machine is supported. This is done by forming the yoke with trunnions a", which pass through suitable bearings a on the base a or it may be done by making the yoke 0L2 of resilient metal, which will yield sufficiently. The spring a maybe employed, if desired, to keep the forward end of the machine pressing onto the base, or it may be found that the weight will be sufficient for this purpose. By this construction the forward or operating parts of the machine may be raised by means of the handle 0 and the material to be operated upon inserted under the U-shaped frame 6, the crossbar 6 and the front of the U-shaped frame being adjusted to the proper distance to hold the material. I also provide the shaft or trunnion cl with a central opening in which there is inserted a pointed centering-rod d. This centering-rod d" is fitted into the opening of the shaft so as to remain by friction in any position.

In operating the machine just described the material to be worked upon is placed under the frame 6 and is held there by the respective sides of the frame. The head is turned, as shown in Fig. 3, with the bar 01' extending across the machine. The centering-rod d" is lowered, and the point which the center of the figure is to occupy is brought opposite the point of the centering-rod. The knife or other tool is then adjusted laterally until the point of the knife is on a horizontal line passing through the center of the centering-rod d. The adjustments of the respective heads 61 and d are then made on the bars (1 and (Z to form the major and minor axes of the figure, if it is to be an ellipse, and

WllOL the bars are secured in their positions the machine is operated byturning the head d through the medium of the handle-bar 01 to which is attached the trunnion on the head d substantially as described in the former patent, and set-screw (1 passes through said trunnion and engages the bar d to hold the head in proper posit-ion. The spring d is employed to furnish the necessary downward movement to allow the tool to contact with the material and follow the outline of the figure.

By the constructions described I can not only outline the various forms and figures, but can readily cut through any reasonable thickness of paper or other material for mats or similar devices. The tool being swiveled in the tool-holder will readily follow and cut out any desired curve, making a clean incision. By the adjustments described it is possible to readily center the work and insure the figure being properly located upon the material operated upon.

Th: machine .iescribed is particularly adapted for cutting oval and similar mats and also for cutting similarly-shaped glass for picture-framing and similar purposes.

Having thus described my invention, I claim- 1. In a cutting-machine, the combination of a tool and a swivel-mount therefor, the blade of said tool being inclined laterally with its cutting edge extended rearwardly from theswivel-mountandconstituting means for free bevel-curve cutting.
